Patient privacy assured by electronic censor

24.07.2008
Newly developed software will help to allay patients’ fears about who has access to their confidential data. Research published today in the open access journal BMC Medical Informatics and Decision Making describes a computer program capable of deleting details from medical records which may identify patients, while leaving important medical information intact.

Patient records that are to be shared within the research community must have any identifying information removed. Manual removal of identifying information is prohibitively expensive and time consuming. Considerable research by many investigators has focussed on developing automated techniques for “de-identifying” medical records.

A team from the Massachusetts Institute of Technology (MIT) funded by the National Institutes of Health (NIH) aimed to solve this problem, pointing out that: “Text-based patient medical records are a vital resource in research. The expense of manual de-identification, coupled with the fact that it is time-consuming and prone to error, necessitates automatic methods for large-scale de-identification.”

The MIT team tested their censoring software on a meticulously hand-annotated database of 1836 nursing notes (a total of 296,400 words). According to the authors, “The software successfully deleted more than 94% of the confidential information, while wrongly deleting only 0.2% of the useful content. This is significantly better than one expert working alone, at least as good as two trained medical professionals checking each other’s work and many, many times faster than either.”

The MIT team is also providing access to the fully-scrubbed annotated data together with the software to allow others to improve their systems, and to allow the software to be adapted to other data types that may exhibit different qualities.

Im Focus: Interfacial Superconductivity: Magnetic and superconducting order revealed simultaneously

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
